Water is also supplied inside. When the motor 30 is rotated to rotate the inner tub 19 around the vertical direction as the rotation center axis, the washing liquid between the inner tub 19 and the outer tub 22 is pushed up by centrifugal force due to this rotation. It is filled in the receiving cover 24, the direction is changed by the rectifying member 31 by further pushing up by the centrifugal force, and is discharged into the inner tank 19.

An outer tub that rotatably houses the inner tub, and a coupling fixed to the lower surface of the bottom of the inner tub and connected to a resiliently supported motor, and a substantially cylindrical washing rod is rotatable at the bottom of the inner tub. The buffer wing is attached to the lower end of the washing shaft connected to the washing bar, and the buffer wing is rotatably held in a buffer case filled with a highly viscous buffer solution. The washing water between the outer tub and the inner tub is circulated and dropped from above, and the fir-wash effect is generated due to the rotation difference between the washing rod and the inner tub, improving the cleaning performance and damaging the perishable laundry. Can be washed and rinsed without having to It can be carried out in. further,
The structure can be simplified, the number of parts can be reduced, and the cost can be reduced.
